(First embodiment)
1. Outline of Opening/Closing Window In the present embodiment, an example of the opening/closing window according to the present disclosure is applied to an inwardly-tilting window in which a shoji (paper sliding door) falls toward the interior side. As shown in FIG. 1, the opening/closing window 1 according to the present embodiment includes at least a frame 3, a shoji 5, a state holding mechanism 7, an operation portion 9, and the like.

The frame 3 is a member that borders the window opening 1A. The frame 3 according to this embodiment is a rectangular frame made of light metal such as aluminum. The shoji 5 swings between a state in which the window opening 1A is closed and a state in which the window opening 1A is opened (the state shown in FIG. 1 and the like).

The shoji 5 according to this embodiment swings around the lower end of the shoji 5 so that the upper end falls toward the room. The side frames 3A, 3B or the lower frame 3C of the frame 3 are provided with support portions (not shown) that support the shoji 5 so as to be swingable.

When the user unlocks the lock mechanism (not shown), the shoji 5 is oscillatingly displaced by the force of gravity acting on the shoji 5 so that the upper end falls toward the inside of the room. In addition, a locking mechanism is a mechanism which hold|maintains the shoji 5 in the position which closes 1 A of window openings.

2. State retention mechanism <Overview of state retention mechanism>
The state holding mechanism 7 is a mechanism for holding the shoji 5 in the first state (see FIG. 2) or the second state (see FIG. 3). In the first state and the second state, the upper end of the shoji 5 is tilted toward the room, and the window opening 1A is opened.

As shown in FIG. 3, the shoji 5 in the second state is located lower than the shoji 5 in the first state (see FIG. 2), and the window opening 1A is larger than that in the first state. open. The operation part 9 is a part operated by the user when canceling the first state.

The operation part 9 is arranged on the front side of the shoji 5 . "The front of the shoji 5" is a portion of the shoji 5 facing the room in this embodiment. Therefore, the shoji 5 according to the present embodiment is oscillatingly displaced so as to fall down on the front side of the shoji 5 .

As shown in FIGS. 4 and 5, the state holding mechanism 7 includes at least a swing arm 71, a lock plate 72, and the like. The swinging arm 71 is an arm-shaped member that swings in conjunction with the swinging displacement of the shoji 5 .

One end (upper end) of the swing arm 71 is rotatably connected to the frame 3 . The other end (lower end) of the swing arm 71 is rotatably connected to the shoji 5 via a fixing bar 70 . A connecting portion between the swing arm 71 and the frame 3 is slidable with respect to the frame 3 . The fixed bar 70 is a member fixed to the frame of the shoji 5 .

The lock plate 72 is an example of a lock member arranged on the side surface of the shoji 5, as shown in FIGS. The lock plate 72 is displaceable between an engagement position (see FIG. 4) and a release position (see FIG. 5).

The engagement position is a position where the lock plate 72 and the swing arm 71 are engaged. The disengaged position is a position where the engaged state is disengaged from the engaged position. When the lock plate 72 is in the engagement position, the shoji 5 is held in the first state. When the lock plate 72 is in the unlocked position, the shoji 5 is in a swingable state to the second state.

<Details of the state retention mechanism>
As shown in FIG. 6, the state holding mechanism 7 has a swing arm 71, a lock plate 72, a return spring 73, guide pins 74A and 74B, and the like. The return spring 73 exerts elastic force to hold the lock plate 72 at the engagement position.

Specifically, one end of the coil spring-like return spring 73 is connected to the lock plate 72 via a fastener 73A such as a P screw, and the other end is connected to the fixed bar 70 via a guide pin 74A. .

The return spring 73 is configured to increase the amount of elastic deformation when the lock plate 72 is displaced from the engagement position toward the release position. Therefore, the return spring 73 always applies an elastic force to the lock plate 72 to displace the lock plate 72 toward the engagement position.

The guide pins 74A and 74B are fixed to the fixed bar 70 and regulate the displacement direction of the lock plate 72 and the displacement direction of the operating portion 9 . That is, the operation portion 9 is provided with long holes 9A and 9B into which the guide pins 74A and 74B are inserted. The major axis direction of the elongated holes 9A and 9B is substantially parallel to the operation direction.

The operation direction is a direction parallel to the direction from the front side of the shoji 5 to the back side of the shoji 5 . Therefore, the operation portion 9 can be displaced parallel to the operation direction and cannot be displaced in a direction perpendicular to the operation direction.

The lock plate 72 is also provided with elongated holes 72A, 72B into which the guide pins 74A, 74B are inserted. The major axis direction of the elongated holes 72A and 72B is a direction inclined with respect to the operation direction. The tilt direction is a direction that satisfies the following requirements.

That is, when the pressing force F (see FIG. 4) directed from the front side of the shoji 5 toward the back side of the shoji 5 acts on the lock plate 72, the lock plate 72 is moved from the engagement position side to the release position side. It is the direction to displace to .

The operation portion 9 has an operation surface 9C, a pressing portion 9D, and the like. As shown in FIG. 2, the operation surface 9C is located on the front side of the shoji 5. As shown in FIG. The pressing portion 9D is located on the back side of the shoji 5, and transmits the pressing force to the lock plate 72 when the pressing force F acts on the operation surface 9C.

For this reason, as shown in FIG. 7, the operation part 9 is configured in a shape extending from the lock plate 72 side (back side of the shoji 5) to the front side of the shoji 5 via the side surface of the shoji 5. As shown in FIG. That is, the operation surface 9C, the pressing portion 9D, and the portion 9E connecting the operation surface 9C and the pressing portion 9D form a U-shaped or U-shaped cross-sectional shape (see FIG. 6).

When the lock plate 72 is in the engaged position, the projection 71A of the swing arm 71 engages with the corner of the lock plate 72 as shown in FIG. A portion of the protrusion 71A that contacts the lock plate 72 is provided with a contact surface 71C substantially orthogonal to the direction of the pressing force F. As shown in FIG.

Therefore, when the swing arm 71 and the lock plate 72 are engaged with each other, even if the pressing force F acts on the operation portion 9, the force displacing the lock plate 72 toward the release position, that is, the contact surface No force is generated in the lock plate 72 that is inclined with respect to 71C.

In other words, the state holding mechanism 7 is configured such that the displacement of the lock plate 72 is restricted when the swing arm 71 and the lock plate 72 are engaged with each other. In other words, the projecting portion 71A functions as a release/stop mechanism that disables release of the first state when the shoji 5 is in the first state.

<Operation of the state holding mechanism>
2 and 4, when the lock plate 72 is in the engaged position, the protrusion 71A of the swing arm 71 is engaged with the corner of the lock plate 72, so that the shoji 5 is in the first state. is held to

When the user presses the shoji screen 5 toward the back side, the engagement between the lock plate 72 and the protrusion 71A is released. Therefore, when the pressing force F acts on the operation portion 9 (operation surface 9C) while the shoji 5 is pressed to the back side, a force is generated to displace the lock plate 72 toward the release position.

As a result, the lock plate 72 is displaced to the release position side (see FIGS. 3 and 5), and the shoji 5 is in a state in which it is opened more than in the first state by the gravity acting on the shoji 5, that is, in the second state. can be.

When the shoji 5 shifts from the first state to the second state, and when the shoji 5 shifts from the second state to the first state, the upper end 72C of the lock plate 72 forms an arc-shaped sliding surface. Sliding contact with 71B.

Then, when the user presses the shoji 5 in the second state in the closing direction, the sliding surface 71B is in sliding contact with the upper end 72C of the lock plate 72, and the swing arm 71 is raised. When the protrusion 71A climbs over the upper end 72C of the lock plate 72, the lock plate 72 is moved to the engagement position by the elastic force of the return spring 73. As shown in FIG.

3. Features of the Opening/Closing Window According to the Present Embodiment In the opening/closing window 1 according to the present embodiment, the operating portion 9 operated when canceling the first state is arranged on the front side of the shoji 5 . As a result, with the opening/closing window 1, it is possible to improve the workability of the unlocking operation.

The operation part 9 extends from the lock plate 72 side to the front side of the shoji 5 via the side surface of the shoji 5 . As a result, a person who provides the opening/closing window 1 can easily arrange the operation part 9 in the opening/closing window 1 while using the existing frame 3 without newly providing a hole or the like in the frame 3 or the shoji 5. it may be possible to

The state holding mechanism 7 is configured to release the first state when the operating portion 9 is pressed and displaced in the operating direction. Therefore, the user can easily cancel the first state.

(Second embodiment)
<Overview of this embodiment>
As shown in FIGS. 8 to 11, the opening/closing window 1 according to this embodiment includes a release maintaining mechanism 11 and a notification section 13 in addition to the configurations shown in the above embodiments.

In addition, the following description is about differences from the opening/closing window 1 according to the above-described embodiment. The same reference numerals as in the above-described embodiment are attached to the same constituent elements as in the above-described embodiment. Therefore, redundant description is omitted in this embodiment.

The release maintaining mechanism 11 is a mechanism for maintaining the shoji 5 in a swingable state when the operation portion 9 is operated. The notification part 13 is a part for notifying that the shoji 5 is in a "swingable state" when the operation part 9 is operated and the shoji 5 is in a "swingable state".

<Details of the release maintenance mechanism>
The release maintaining mechanism 11 has at least a release maintaining member 111, a maintaining spring 112, and the like. The release maintaining member 111 is a member that can be engaged with the lock plate 72 when the lock plate 72 is at the release position.

The release maintaining member 111 can be displaced between a first position (see FIG. 10) in which it can be engaged with the lock plate 72 and a second position (see FIG. 8, etc.) in which the engagement is released. Specifically, it is as follows.

That is, as shown in FIG. 12, the lock plate 72 according to this embodiment is provided with a concave portion 72D. The release maintaining member 111 is provided with an engaging portion 113 that can be engaged so as to fit into the recess 72D.

The release maintaining member 111 is rotationally displaced between the first position and the second position while being rotatably supported by the guide pin 74B. That is, the rotation center position of the release maintaining member 111 is immovable with respect to the shoji 5 .

Then, as shown in FIG. 10, the release maintaining member 111 is at the first position when the engaging portion 113 is fitted into the recess 72D. As shown in FIGS. 8, 9 and 11, when the engaging portion 113 is disengaged from the recess 72D, the release maintaining member 111 is in the second position.

Displacement of the lock plate 72 is restricted in a state where the engaging portion 113 is fitted into the recess 72D. Therefore, in this state, the lock plate 72 is maintained at the released position. When the engaging portion 113 is disengaged from the concave portion 72D, the lock plate 72 can be displaced according to the operation of the operating portion 9. As shown in FIG.

The maintenance spring 112 applies an elastic force to the release maintenance member 111 to maintain the release maintenance member 111 at the first position. The maintenance spring 112 according to this embodiment is a tension coil spring.

A component in a direction intersecting the direction of the elastic force of the maintaining spring 112 functions as an elastic force for maintaining the release maintaining member 111 at the first position. The return spring 73A exhibits the same function as the return spring 73.

<Notification part>
The notification portion 13 emits a sound (hereinafter referred to as a notification sound) for notifying that the engaging portion 113 is fitted into the concave portion 72D to indicate that the "swingable state" has been achieved. That is, when the engaging portion 113 is fitted into the recess 72D, the lock plate 72 is maintained at the unlocked position, so the notification portion 13 emits a notification sound.

The notification unit 13 according to the present embodiment emits a collision sound when the engagement portion 113 collides with another member when the engagement portion 113 plunges into the recess 72D due to the elastic force of the maintenance spring 112. and

<Opening operation of opening/closing window>
When the opening/closing window 1 is in the closed state, that is, when the shoji 5 is in the closed state, as shown in FIG. Member 111 is in the second position.

In the closed state, when a closing mechanism (not shown) for maintaining the closed state of the shoji 5 is released, gravity acting on the shoji 5 causes the shoji 5 to move into a chamber on the upper end side with the lower end side as the center. It rotates and displaces so that it falls inward.

As the swinging arm 71 rotates with respect to the shoji 5 as the shoji 5 rotates, the protrusion 71A engages with the corner of the lock plate 72, so that the shoji 5 is in the second position as shown in FIG. It is held in the 1 state.

In the state shown in FIG. 9, the release maintaining member 111 is at the second position. Therefore, when the user presses the shoji 5 toward the back side, that is, when the engagement between the rocking arm 71 and the lock plate 72 is released, a pressing force F (see FIG. 4) is applied to the operating portion 9. When acted upon, the lock plate 72 is displaced to the release position.

Then, when the lock plate 72 is displaced to the release position and the concave portion 72D provided in the lock plate 72 reaches a position where it can be engaged with the engaging portion 113 provided in the release maintaining member 111, the elasticity of the maintaining spring 112 is reached. Due to the force, the engaging portion 113 plunges into the recess 72D.

As a result, the collision sound emitted when the engaging portion 113 is thrust into the vehicle is notified as a warning sound, and the elastic force of the return spring 73A returns the lock plate 72 to the engaging position as shown in FIG. Regulated.

When the shoji 5 is further rotated indoors from the state shown in FIG. 10, the release maintaining member 111 is pressed by the pressing portion 71D and displaced from the first position to the second position as shown in FIG. As a result, the engaging portion 113 is disengaged from the concave portion 72D.

When the engaging portion 113 is disengaged from the recess 72D, the engaging portion 113 is engaged with the fixing bar 70 or the lock plate 72 so as to be restricted from being fitted into the recess 72D (see FIG. 11). ).

The pressing portion 71D is provided on the swing arm 71 and displaces integrally with the swing arm 71 . The force with which the pressing portion 71D presses the release maintaining member 111 is the force with which the swing arm 71 rotates, that is, the force with which the shoji 5 is rotationally displaced toward the room.

<Closing operation of opening/closing window>
In the state shown in FIG. 11, when the user applies a force in the direction of closing the shoji 5 to the shoji 5, the shoji 5 is rotationally displaced in the order of FIG. 11→FIG. 9→FIG.

The engagement portion 113 is locked by the fixing bar 70 or the lock plate 72 and is restricted from being fitted into the recess 72D. Therefore, unless the user applies a pressing force F (see FIG. 4) to the operating portion 9, the engagement portion 113 is kept in a state of being separated from the recess portion 72D.

When the shoji 5 is rotationally displaced in the closing direction, the protrusion 71A of the swing arm 71 is displaced away from the lock plate 72, so that the swing arm 71 and the lock plate 72 are engaged. never.

<Characteristics of the opening/closing window according to the present embodiment>
The opening/closing window 1 includes a release/maintaining mechanism 11 for maintaining the shoji 5 in a swingable state when the operating portion 9 is operated. In other words, the opening/closing window 1 according to this embodiment is maintained in the first state unless the operating portion 9 is operated. Therefore, it is possible to prevent problems such as the lock plate 72 returning to the engagement position at a timing unintended by the user after the first state is released.

The opening/closing window 1 is provided with a notification part 13 for notifying that the shoji 5 is in a "swingable state" when the operation part 9 is operated and the shoji 5 is in the "swingable state". As a result, the user can reliably perceive that the "rockable state" has been reached.

The opening/closing window 1 has a release/stop function that makes it impossible to release the first state when the shoji 5 is in the first state. As a result, it is possible to prevent the shoji 5 from entering a "swingable state" without the user's intention.

(Third embodiment)
The opening/closing window 1 according to the above-described embodiment is an opening/closing window provided with a release/stop function that makes it impossible to release the first state when the shoji 5 is in the first state. On the other hand, the opening/closing window 1 according to the present embodiment is an opening/closing window in which the release stop function is abolished.

The following description relates to differences from the opening/closing window 1 according to the above-described embodiment. In addition, the same code|symbol as the above-mentioned embodiment is attached|subjected to the same component as the above-mentioned embodiment.

A contacted surface 72E is formed of a surface substantially parallel to the longitudinal direction of the long hole 72B.

In the first state, that is, the state shown in FIG. 13, when the pressing force F (see FIG. 4) acts on the operating portion 9, the contacted surface 72E can be slidably displaced with respect to the contact surface 71C. Therefore, when the pressing force F acts on the operation portion 9, the lock plate 72 is displaced to the release position without the user pressing the shoji 5 to the rear side.

As a result, the user can easily bring the shoji 5 into a "swingable state". In the above-described embodiment, the contact surface 71C is substantially orthogonal to the direction of the pressing force F, so even if the pressing force F acts on the operating portion 9, the lock plate 72 is displaced toward the release position. hard to do
